Ive had some variable lower back pain going on for about 3 weeks. Ive alturnated between tens unit, epsome salt/peppermit oil baths, massage, ice packs, stretching excercises. With a little relief. I finally resorted to 37.5mgs of ultram. However i can feel golf ball sized lumps on either side of my spine, they are squishy and move around a bit when rubbed. They feel good when i rub them and even better when i push on them hard and stretch. Should i be conserned about these lumps? Any advise on how to get rid of the pain permanently?
